US Patent 11952312 Low-modulus ion-exchangeable glasses for enhanced manufacturability

Glass compositions are provided with low Young's modulus and compatibility with slot drawing techniques, due at least in part to liquidus viscosity and liquidus temperature. When ion-exchanged the resulting glass articles are capable of exhibiting a ratio of a peak compressive stress value in MPa to a Young's modulus value in GPa of 13.0 or more. The glass articles may have a peak compressive stress value in a range of 850 MPa to 1400 MPa. The glass articles are suitable for various high-strength applications, including cover glass applications that experience significant bending stresses during use, for example, cover glasses for flexible displays.
